A test was conducted to determine whether gender of a spokesperson affected the likelihood that consumers would prefer a new product.  A survey of consumers at a trade show employing a female spokesperson determined that 70 out of 1500 customers preferred the product, while 62 of 180 customers preferred the product when a male spokesperson was employed.  At the 0.01 level of significance, do the samples provide sufficient evidence to indicate that on the average, fewer consumers prefer a new product when the spokesperson is female?
